Subject: [PATCH 5.11 163/210] ARM: dts: turris-omnia: fix hardware buffer management

From: Rui Salvaterra <rsalvaterra@...il.com>

[ Upstream commit 5b2c7e0ae762fff2b172caf16b2766cc3e1ad859 ]

Hardware buffer management has never worked on the Turris Omnia, as the
required MBus window hadn't been reserved. Fix thusly.

Fixes: 018b88eee1a2 ("ARM: dts: turris-omnia: enable HW buffer management")
